If an alpha particle (two protons and twoneutrons) is given an initial (nonrelativistic) velocityvat a very far distance and is aimed directly at a gold nucleus(Z=79), what is the closest distance d the alpha particle will come to the nucleus?In this problem you can estimate that the mass of the proton m_p is equal to the mass of the neutron and only consider theeffects of a single gold nucleus. Assume that the alpha particle comes close enough so that the nucleus is not substantiallyscreened by inner-shell electrons.Express your answer in terms ofm_p, the permittivity of free space epsilon_0, the magnitude of the electron charge e, and v.

Snug Harbor Realty Co., had a checking account in 1st National Bank. When construction work was obtained by Snug Harbor, its superintendent, Magee, would examine the bills submitted for labor and materials. He would instruct the bookkeeper which bills were approved, and the bookkeeper then prepared the checks in accordance with his instructions. After the checks were signed by the proper official of Snug Harbor, Magee picked them up for delivery. Instead of delivering certain checks, he forged the signatures of the respective payees as endorsers and cashed the checks. The drawee bank then debited the Snug Harbor account with the amount of the checks. Snug Harbor claimed this was improper and sued the bank for the amount of the checks. The bank claimed it was protected by the impostor rule. Required:Will the bank be successful?
